OK..
I have two blocks in the drawing,
one named DEMOLITON and one named FORCONSTRUCTION
I paisted
(remstamp "REMBLOCK,FORCONSTRUCTION")
and
(remstamp "DEMOLITION,FORCONSTRUCTION")
both times the purge seems to run but then I get this at the command prompt
I even typed it in instad of paisting .. i attached the lsp and the DWG.
Command: ; error: bad argument type: consp "REMBLOCK,FORCONSTRUCTION"
Command: ; error: bad argument type: consp "DEMOLITION,FORCONSTRUCTION"
I even re-copied your code, resaved the .lsp file, and reloaded the lsp. and ran it a second time...
something.. aint right.
